this is a small demo I've been working on...it's a flying KinematicBody in arcade style...no realistic simulation , the script is very simple...is implemented shooting and also simple changes in speeds, I also added the enemy which tracking the player.
.....I prepare the files and give it to github to download for community(MITlicense)
....assets are low poly...nothing great but fulfills the purpose
....demo was created in Godot v3.1 alpha1.... so they can be bugs....for example projectiles after collision with the surface will not disappear(yet the error may be on my side )
...also enemy script is not perfect.
....everything is meant for beginners who want something to fly 3D and they do not know where to start ... when I started with Godot engine so I just wished to have such a demo available.
